The ability of some bacteria and filamentous fungi to degrade aniline and its derivatives was reported earlier in the literature. However, there was no information about the biodegradation of aniline by yeast strains. The present work is focused on yeast strain Candida methanosorbosa BP-6 which was isolated from the wastewater pool of the old dye factory "Boruta" in Zgierz by enrichment techniq...

Aniline and o-, m-, and /Moluidine, which are representative of aro matic amines in cigarette smoke, were identified and quantified in human urine. Smokers excreted 3.1 ±2.6 «¿g/24 h of aniline and 6.3 ±3.7 ¿ig/ 24 h of o-toluidine (n = 16). Nonsmokers excreted 2.8 ±2.5 Mg/24 h of aniline and 4.1 ±3.2 un; 24 h of o-toluidine (n = 12). Metaand /»toluidine were detected in the urine of 2 ...

O mecanismo de redução do composto N-fenil-4-nitrobenzenosulfonamida foi investigado em meio aquoso por polarografia de corrente direta e pulso diferencial, voltametria cíclica e coulometria a potencial controlado. Em pH < 10, o composto é reduzido em uma única etapa de 4 elétrons. Entretanto duas etapas de redução são verificadas em elevados valores de pH (pH > 11). A redução do grupo ni tro à...

The tetra(ethylene glycol) derivative of benzothiazole aniline, BTA-EG4, is a novel amyloid-binding small molecule that can penetrate the blood-brain barrier and protect cells from Aβ-induced toxicity. However, the effects of Aβ-targeting molecules on other cellular processes, including those that modulate synaptic plasticity, remain unknown. We report here that BTA-EG4 decreases Aβ levels, alt...

We have characterized a novel microorganism, strain HY99, which is capable of aerobic and anaerobic degradation of aniline. Strain HY99 was found to aerobically metabolize aniline via catechol and 2-hydroxymuconic semialdehyde intermediates, and to transform aniline via p-aminobenzoate in anaerobic environments. Physiological and biochemical tests revealed that strain HY99 was most similar to D...

The reaction of [Mo(η-C5Me5)Cl4] with the ortho-, meta-, or para-iodo-functionalized anilines 2-IC6H4NH2, 3-IC6H4NH2, 4-IC6H4NH2 yields imido amine products type [Mo(η-C5Me5)Cl2(IC6H4N)] (2-I, 1, 3-I, 3, 4-I, 5) [Mo(η-C5Me5)Cl4(IC6H4NH2)] (3-I, 2, 4), respectively, depending on stoichiometry/conditions; we were unable to isolate an complex 2-I derivative. one equivalent 2-I,4-FC6H3NH2 in presen...

Synthetic and biological amines such as ethylenediamine (EDA), spermine, and spermidine have not been previously investigated in free-radical biochemical systems involving aniline-based drugs or xenobiotics. We aimed to study the influence of polyamines in the modulation of aromatic amine radical metabolites in peroxidase-mediated free radical reactions. The aniline compounds tested caused a re...

the synthesis and properties of new monoazo dyes derived from the diazonium salts of paminobenzoic acid, 3-trifluoromethyl aniline , 4-trifluoromethyl aniline are considered .theprepared compounds were characterized by uv-visible , ft-ir and h nmr spectroscopictechniques . the effect of varying solvent upon the absorption ability of p-amino benzoic acidcoupled with 4,4 —diethyl aniline , anilin...

A high-throughput multiparameter optimization of chemical oxidative polymerization conditions has been developed for a facile synthesis of furan homopolymers and furan/aniline copolymers using a combinatorial method. The polymerization yield, molecular structure, and properties of the polymers would be optimized against typical polymerization parameters, including oxidant species, medium specie...
